Table 2. Measured ultrasonic velocities (Wang and Nur, 1991) for a
sequence of binary
hydrocarbon mixtures at 20
C compared to velocities computed
using Wood's formula, the time average equation, and a simple mixing rule.
Data required for computing Wood's formula may be found in Table 1.
The formula for the 1-decene/1-octadecene hydrocarbon mixture is
(
C10H20)
x(
C18H36)
(1-x), where
x is the volume
fraction of 1-decene. Units of all velocities are km/s.

Wood's formula, the time average equation, and a simple mixing rule.
Data required for computing Wood's estimate may be found in Table 1.
Units of all velocities are km/s.
